So, when you go to look at our Kara DKP there's a guy there named Lanir. If you click on the "Name" column to resort by name Lanir disappears. It also happens if I click on almost any other column to resort.

It looks like it's because he doesn't have a class assigned to his toon.

I could understand him disappearing if I had sorted by class (although ideally he should just be at the bottom of the list), but it's by name. It shouldn't be excluding him at all in my opinion. Just stick him at the bottom of the list.
